Desa'a multispecies AGB from stump diameter DSH (M9)
As printed (Table 3 (a, b, adj-R2, rRMSE, rBias, AIC))
In this library's units, ready to compute (kg)
Aboveground biomass = 0.17 * D30^2.128D30- Stem diameter at 30 cm, cm
DSH is the diameter at stump height, 0.3 m above ground, mapped to D30. Recommended by the authors for simplicity with M1. Multi-stem trees combine stems as in the paper (Eq. 1). Adjusted R2 0.941. The fits were done on ln-transformed data and the paper says predictions were back-transformed with a correction factor (CF from RSE) for its error statistics, but it does not print the CF or say whether the tabulated a already includes it; no cf is entered. Adjusted R2 is given in the notes, not fit.r2, because it is adjusted.
